Title: Bistable pin actuator
Inventor: SUMINO KAZUYOSHI
IPC: H02K33/12
Filed: 1993-12-14
Abstract: PURPOSE:To provide a pin actuator which improves the reliability of operation with small power consumption by supplying first and second coils, which are connected in series and the directions of whose winding are reverse, with currents in first and second directions, respectively, for specified time. CONSTITUTION:In the case that a pin 26 is in the first stable position and that it maintains the stable condition, coils 34 and 36 are not supplied with currents. Accordingly, the pin 26 is attracted to a plate-shaped member 22 by the magnetic force line generated from a permanent magnet 30. And, in the case of shifting the pin 26 from the first stable position to the second stable position, the magnetic field above the permanent magnet 30 strengthens and the magnetic field below it weakens by letting the current is specified direction to the coils 34 and 36 connected in series, so the pin 26, which offsets the magnetic field by the coil 36 and the magnetic field by the permanent magnet, shifts to the specified position, being attracted by the plate-shaped member 20, by adjusting the magnitude of the current. As a result, only in the case of shifting the pin, power is required, thus a pin actuator where the power consumption is small and the reliability of operation is improved, can be gotten.

Title: Charge pump type boosting circuit
Inventor: HARAGUCHI YOSHIZUMI
IPC: H04N5/374
Filed: 1998-12-03
Abstract: PROBLEM TO BE SOLVED: To eliminate the fluctuation of an output voltage synchronized with drive pulse. SOLUTION: While an overlap capacitor Co1 between the gate of an NMOS transistor M3 and a circuit output terminal 3 is connected between an output terminal N2 and a circuit output terminal 3, an overlap capacitor Co4 between the gate of a newly added NMOS transistor M4 and the circuit output terminal 3 is connected between an output terminal N1 and the circuit output terminal 3. Therefore, the fluctuation of the output voltage which is in synchronization with the voltage change in a voltage V2 (in synchronization with a drive pulse ϕ2) is canceled by the fluctuation of an output voltage, in synchronization with the voltage change (change in a voltage V1) of the inverse phase of the voltage V2 that is generated via the capacitor Co4 simultaneously, thus always making an output voltage VOUT constant.
